To be able to determine the number of moles that a certain number of molecules comprises, we simply divide the number of molecules by the Avogadro's number which is equal to 6.022 x 10^23.
n = M/A
where n is the number of moles, M is the number of molecules, and A is Avogadro's number. Substituting the known values,
n = (4.15 x 10^23 molecules)/(6.022 x 10^23 molecules/mol)
Simplifying,
n = 0.689 moles
<em>Answer: 0.689 moles</em>
I think it's false I'm just guessing
Answer:
The energy can be used in a redox reaction
Explanation:
When electrons in photopigments become excited, what is the result of the energy input?
The energy can be used in a redox reaction. The energy can be transferred to a nearby pigment. They can cause fluorescence or heat emission

Aluminum's outer electron in 3p-orbital is slightly further from the nucleus and protected by 3s-orbital. This causes it to need less energy. Magnesium's outer electron is closer and not protected by an outer orbital.
Hope This Helps and Ged Bless!
